    Sammanfattning : Paper 1: Improving Welfare Through Climate-Friendly Agriculture: The Case of the System of Rice Intensification We use rich survey data to investigate the economic impact of a climate-friendly rice farming method known as the system of rice intensification (SRI) on the welfare of rain-dependent small-holder farmers in Tanzania. SRI reduces water consumption by half, which makes it a promising farming system in the adaptation to climate change in moisture constrained areas, and it does not require flooding of rice fields, resulting in reduced methane emissions.

  7. 5. Fire history in the hemiboreal and southern boreal zones of southern Sweden during 11000 years : Relationships with past vegetation composition and human activities and implications for biodiversity issues

    Författare :Qiao-Yu Cui; Marie-José Gaillard; Boris Vannière; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fire history; land-use history; biodiversity; charcoal analysis; Landscape Reconstruction Algorithm LRA ; Holocene; Småland; Sweden; Paleoecology; Paleoekologi;

    Sammanfattning : This thesis studies fire history over the last 11 000 years (Holocene) in central Småland, southern Sweden, on the basis of palaeoecological analyses of peat sequences from three small bogs (Notteryd, Stavsåkra and Storasjö). The main objective is to gain insights into the long-term relationships between fire, climate, human-impact, other environmental factors and the history of biodiversity in the study region. LÄS MER
